Overview: Electronic programme guides
Electronic programme guides connect channel identity with scheduled events, source data and time conventions.
A guide entry needs the right channel and the right time interpretation before it can support a recording decision. Programme IDs and schedule changes add further relationships as the listing evolves. This branch explains those mappings so a correct-looking title is not mistaken for a fully matched recording event.
What is an EPG?
An electronic programme guide associates stations and time intervals with programme descriptions, supplying the schedule information used for browsing and programme-based recording.Guide sources and formats
Guide sources and formats encode programme schedules and supporting service information through different conventions.Channel mapping
Channel mapping associates a selectable source service with the corresponding guide station, preserving station and provider context when names or numbers are ambiguous.Programme identifiers
Programme identifiers distinguish series, episodes and scheduled airings within a provider or broadcast context, enabling reliable joins without treating titles or local IDs as universal keys.Guide time zones
Guide time zones determine how supplied date/time values become absolute instants and local display times, including repeated or missing clock times around daylight-saving changes.Programme schedule changes
Programme schedule changes revise the station, time or content associated with an airing, requiring the loaded guide and recording plan to be evaluated separately.
